A new lightweight, small-footprint coiled tubing unit (CTU) has been developed to enable CT for a broad spectrum of well service applications. The technology could substantially reduce well intervention costs, logistical support and risk exposure and can be applied to operating environments worldwide, ...
In the Malay Basin area, 18 offshore oil and gas fields are operated by PETRONAS Carigali Sdn. Bhd (PCSB). PCSB performs well intervention, integrity operations and maintenance on 41 platforms comprising of 748 strings. In these mature assets, total production figures are approximately 100,000 bbls/day ...
This paper summarizes a three-year research on the overtrawlability of pipe-in-pipe, and develops the method to access it. Overtrawlablity is the ability of the pipe to resist the trawl gear impact and the pull-over force. The trawl gear will first impact the pipe and then pull over the pipe. If the ...
Kuwait Oil Company (K.O.C.) had major issues in resolving issues of controlling water production from long strings in dual completion wells. An economic process of zonal isolation was being searched for by the Company since conventional process of mobilizing a work over rig is expensive and would also ...
Predation may create strong natural selection pressure on the phenotype and life history characteristics of prey species. The Izu scincid lizards (Plestiodon latiscutatus) that inhabit the four Japanese Izu Islands with only bird predators are drab brown, mature later, lay small clutches of large eggs, ...
Understanding how the brain transforms sensory input into complex behavior is a fundamental question in systems neuroscience. Using larval zebrafish, we study the temporal component of phototaxis, which is defined as orientation decisions based on comparisons of light intensity at successive moments ...
The aim of this study was to compare human epidermal growth factor 2 (HER2) status in primary colorectal cancer and paired liver or lung metastasis. Gene amplification of HER2 has been intensively evaluated in contemporary oncology, especially in breast and stomach cancer. The knowledge of HER2 status ...
The use of Dope-Free tubulars in offshore operations have been increasingly adopted by different operators since its debut in the North Sea in 2003. Dope-Free tubulars replaces the storage and running pipe dope historically used in Casing and Tubing by a dry coating applied on pipe threads in an industrial ...
Description ofproposed paper: Burial ofsubmarine pipelines and cables is standard practice in offshore oil and gas regionswhere potentially damaging threats such as interaction with fishing gear anddragged anchors are high. The requirement to bury pipelines in Asia-Pacific hasnot had the same imperative ...
Deepwater subsea waterjet technology provides an opportunity to prepare for tier 2 and tier 3 oil spill emergencies and has been developed to enable safe, efficient and reliable means of addressing common subsea maintenance and repair operations. Deepwater subsea waterjet technology extends well known ...
Background Mitochondria are dynamic organelles that frequently undergo fission and fusion processes, and imbalances in these processes may be involved in obesity and insulin resistance. Aims The present work had the following aims: (a) to evaluate whether the mitochondrial dysfunction present in ...
Survival of incipient non-indigenous populations is dramatically altered by early predation on new colonisers. These effects can be influenced by morphological traits, such as coloniser size and density. The Australian non-native Pacific Oyster Crassostrea gigas is generally more fecund and faster growing ...
Bony bream (Nematalosa erebi) and black catfish (Neosilurus ater) were sampled from the fresh surface waters of the Finniss River in tropical northern Australia, along a metal pollution gradient draining the Rum Jungle copper/uranium mine, a contaminant source for over five decades. Paradoxically, populations ...
The therapeutic effect of polysaccharide of large yellow croaker swim bladder (PLYCSB) on lupus nephritis has been studied in vivo. A high concentration (50 mg/kg dose) of PLYCSB reduced the levels of serum inflammatory cytokine levels of IL-6, IL-12, TNF-α and IFN-γ compared to a low concentration ...
In this review, we aim to explore the potential of microalgal biodiversity and ecology for biotechnological use. A deeper exploration of the biodiversity richness and ecophysiological properties of microalgae is crucial for enhancing their use for applicative purposes. After describing the actual biotechnological ...
Introduction: Fishing is a leisure activity for some people around the world. Accidently the fish hook can get hooked in the hand. If the hook is barbed, removal becomes difficult. We report a case of such a injury in the hand and discuss the technique for its removal with a brief review of the literature. Case ...
Despite some evidence of within-population phenotypic variation in fish thermal behaviour, the occurrence of alternative tactics of this behaviour is rarely explicitly considered when studying natural populations. Brook charr provide an example of within-population variability in behavioural thermoregulation ...
In recent decades, spearfishing with SCUBA has emerged as an efficient method for targeting reef fish in deeper waters. However, deeper waters are increasingly recognised as a potential source of refuge that may help sustain fishery resources. We used a combination of historical catch data over a 20-year ...
The Brownie tag-recovery model is useful for estimating harvest rates but assumes all tagged individuals survive to the first hunting season; otherwise, mortality between time of tagging and the hunting season will cause the Brownie estimator to be negatively biased. Alternatively, fitting animals with ...
The consumption of marine fishes and general seafood has long been recommended by several medical authorities as a long-term nutritional intervention to preserve mental health, hinder neurodegenerative processes, and sustain cognitive capacities in humans. Most of the neurological benefits provided ...
